Construction wastes have become a pressing issue in many developing countries and have adverse effects on environment, economy and social aspects. Illegal dumping is a common issue created from the physical construction waste and besides that non physical waste like cost and time overruns are not properly addressed among the construction players. This paper explores the impacts of construction on sustainable construction and contributing causes which will help the practitioners to formulate ways in avoiding or reducing the waste. It also highlights the sustainable approach in managing the construction waste as practice.
Delays that occur on a construction projects can cause project performance inefficiencies and can even add to the project cost. Factors due to project delays consist of many things that can cause project delays. This study aims to find a top ten similarity factor that causes delays in a construction projects based on the results of research in Jakarta construction projects against previous studies in other countries. From a total of 100 distributed questionnaires, 88 (88%) were filled in correctly and returned as data analysis material. The Data from the survey results were analyzed using Statistical Software Package (SPSS) to produce a ranking for Project Delay Factor. The ranking of the study was then re-analyzed based on the similarity of the previous research so that the similar Project Delay Factor Ranking was obtained.
